search problem in 4.4

I had to modified the cvs version of filestore to support the drupal cvs and correct little bugs

First, the 4.4 version modified the _search hook
it should now return an array of 2 elements:
-a title to sort the results from several type of node
-the actual results

Second a bug in the search was not showing the username in the result because the users table was not joined in the query.

I include a patch I created quickly. The patch also includes another change in the _form hook.
